LLMs-gone-rogue dominated coverage, but had nothing to do with the targeting. Instead, it was choices made by human beings, over many years, that gave us this atrocity

On the first morning of Operation Epic Fury, 28 February 2026, American forces struck the Shajareh Tayyebeh primary school in Minab, in southern Iran, hitting the building at least two times during the morning session. American forces killed between 175 and 180 people, most of them girls between the ages of seven and 12.

Within days, the question that organised the coverage was whether Claude, a chatbot made by Anthropic, had selected the school as a target. Congress wrote to the US secretary of defense, Pete Hegseth, about the extent of AI use in the strikes. The New Yorker magazine asked whether Claude could be trusted to obey orders in combat, whether it might resort to blackmail as a self-preservation strategy, and whether the Pentagon’s chief concern should be that the chatbot had a personality. Almost none of this had any relationship to reality. The targeting for Operation Epic Fury ran on a system called Maven. Nobody was arguing about Maven.

Hair transplants have never been more widespread or more affordable. So why do so many balding men prefer glued-on hairpieces? And are the best really undetectable?

When you hear the word toupee, certain images spring to mind. Older men with suspiciously thick hair, say; or a poorly colour-matched partial wig covering a bald patch, perhaps flying off in the wind. These are the toupees of old.

Toupees are distinct from wigs in that they cover only part of the scalp, but both have a long history. While humans were wearing hairpieces as far back as ancient Egypt, toupees originated in the 18th century, the name developing from the French toupet, meaning “tuft of hair”. They became particularly prominent in the mid-20th century, with Time magazine estimating that more than 2.5 million men across the US were wearing toupees by 1970. But concerns about how obvious the pieces were, hammered home by ridicule in popular culture (see Monty Python’s Toupee Department sketch) combined with the gradual acceptance of shaved heads in fashion, led to their decline.

Noah Wyle is back on our screens as a lovable doctor in the punchy, gory and totally addictive series that has taken the US by storm. Believe the hype!

It’s here at last. The medical drama that took its native US by storm last year has finally crossed the pond. All 15 episodes of The Pitt’s first season, set in almost real time over a single shift in the overstretched emergency department of a busy Pittsburgh hospital, are being offered to tempt us all into subscribing to yet another streaming service – HBO Max, which also promises other baubles, such as the new Harry Potter series and the adaptation of DC Comics’ Lanterns plus rich pickings from its prestigious back catalogue, such as The Sopranos, Succession, Game of Thrones and Friends (which departed Netflix last year, giving many viewers the first insight into the true transience of life).

But The Pitt is the one that we older viewers, perhaps, have been waiting for. For it comes from much the same team that produced the then-groundbreakingly gritty ER, and it stars one of its most enduring talents, Noah Wyle. He arrived in the 1994 pilot episode as third-year medical student John Carter, and we followed him as he endured, then thrived under Dr Benton’s tough-love training, qualified in emergency medicine and moved up the ranks at Cook County before bowing out as a main character in the season finale in 2006. With many a literally heart-stopping moment in between, let me tell you. The show made a megastar out of George Clooney (as womanising paediatrician Doug Ross) but Wyle was never less than brilliant.

A box the size of a filing cabinet was lifted by crane, slowly moved and placed very carefully in the back of an unassuming lorry earlier this week. What looked like a casual drive around the Cern campus was actually a world-first experiment in transporting antimatter, the most expensive and volatile substance on Earth. To find out why scientists wanted to achieve this milestone, and what happened on the journey, Madeleine Finlay hears from the Guardian’s science editor, Ian Sample, and the Cern physicist Dr Christian Smorra.

The Which? travel editor on the unexpected joys and considerable savings of house swapping. Plus top tips on how to do it

Imagine cutting the cost of accommodation on your next holiday to about £5 a day. You can have a whole house, rather than just a bedroom. And you can go almost anywhere in the world and stay as long as you like, within reason. Welcome to house swapping.

You’re sceptical, I know. I was, too. Our terrace house was too small. Too overflowing with stuff. The 1980s kitchen was too old (and battered). We aren’t in a nice enough neighbourhood. Who would want to stay here? Lots of people, it turned out.

As species vanish and the unique ecosystem radically changes, Ukrainian scientists can only wait until it is safe to properly assess the damage

In the embattled harbours of Odesa, a scientific vessel lists in its mooring. No one has been able to take a look at the damage to the Boris Alexander from Russian drones and shelling that have hit the port city over the past four years of war in Ukraine. It is too dangerous, just as no one has been able to fully monitor the damage the war is doing to the Black Sea.

“We can only wait,” says Dr Jaroslav Slobodnik, the director of the Environmental Institute, headquartered in the Slovak Republic. “The biodiversity landscape is completely altered. A number of species seem to have disappeared, but we need more data. Data which the war makes it impossible to collect.”

US president claims Iranian negotiators fear being killed by their own side; Chinese foreign minister says US and Iran ‘signalling a willingness to negotiate’

• Iran rejects US ceasefire plan and submits its own amid push for talks

• Analysis: Trump pitches peace plan but military buildups rarely veer to off-ramp

An Iranian envoy has said South Korean ships can pass through the strait of Hormuz only after coordinating with Tehran, the Yonhap News Agency has reported.

Such an agreement had to be reached in advance of the transit, said Saeed Khuzechi, the Iranian ambassador to South Korea, at a press conference in response to a question about guarantees for South Korean vessels to navigate the vital conduit for oil.

Organisation for Economic Cooperation and Development says UK economy will grow by just 0.7% this year

The conflict in the Middle East will damage the UK’s economy more than any other industrialised nation, according to analysis by the Organisation for Economic Cooperation and Development (OECD), which warned over rising inflation.

In the first major assessment by a leading international thinktank of the economic impact from the attack on Iran, the OECD said the UK economy would grow by just 0.7% this year, compared with its last forecast, made in December, of 1.2% for 2026.

Reluctance to cheerlead alleged US ceasefire efforts reflects suspicion talk of peace could be another foil for escalation

• Middle East crisis – live updates

Not long after Donald Trump said the US was engaged in “strong talks” to bring the war with Iran to an end this week, Qatar took the unusual step of distancing itself from the alleged diplomatic negotiations.

Qatar was not involved in any mediation efforts, said government spokesperson Majed al-Ansari at a briefing on Tuesday night, before adding as a telling aside: “If they exist.”

Meta and YouTube have been found liable for deliberately designing addictive products that hooked a young user and led to her being harmed, a jury ruled on Wednesday. Jurors found the tech companies to be both negligent and having failed to provide adequate warnings about the potential dangers of their products.

The jury awarded the plaintiff in the case damages of $6m, with Meta to pay 70% and YouTube the remainder. It took nearly nine days of deliberations for the Los Angeles jury to reach its verdict. This lawsuit, over social media’s alleged harm to young people, was the first of its kind to go to trial.
